Information timeliness metrics and research progress for 6G network by Jingzhou SUN, Lehan WANG, Yuxuan SUN, Sheng ZHOU, Zhisheng NIU

“…In the future 6G network, machine-type communication will dominate the network traffic.Many vertical applications, such as networked autonomous driving and industrial internet of things, will become new growth points.Such applications usually consist of the collection of status information and distribution of control signals, requiring ultra-low latency.However, this requirement is hard to meet with a large number of end nodes and limited communication resources.In view of this confliction, it was pointed out that the freshness of information should be considered in the status update system instead of just latency.Furthermore, according to the degree of utilization of status information, various measures of information freshness were introduced, and related representative work was summarized.Finally, the future research directions of information freshness and key questions that need to be answered were discussed.…”

Research on elastic handover algorithm of 6G network based on fine-grained slicing by Xiaorong ZHU, Kang CHEN

“…With the emergence of high-bandwidth services such as holographic communication and augmented reality in the future, high-bandwidth services will be divided into finer-grained service slices according to the rates to meet diverse requirements of users.For the problem of how to complete network switching in a fine-grained slicing of large bandwidth services, an elastic handover algorithm of 6G network based on bipartite graph stable matching was proposed.By optimizing “user-network slice-base station” association, the total rate of users was maximized, and the access problem was modeled as a hierarchical bipartite graph stable matching problem.Then by using the two matching ideas of “slice base station” integration and “slice first and then base station”, the adaptive handoff of the network was realized by using Gale-Shapley algorithm.Simulation results show that the access success rates of the proposed integrated and two-stage matching algorithms are 15% and 10% higher respectively than that of the traditional method, and the total rate of users is also significantly improved.…”

“…The deep integration of artificial intelligence (AI) and communication technology is the typical feature of the 6G network.On the one hand, AI injects new vitality into the development of the 6G network, which can effectively use the data generated by the historical operation of the network.It enables the network to be self-maintained and selfoptimized, and accelerates the process of network intelligence.On the other hand, the rich scenarios and IoT devices of the 6G network provide a large number of application fields and massive data for AI.These can enable the better deployment of AI, fully demonstrate the performance advantages of AI, and provide high-quality services for users.However, in practice, it is difficult to give full play to the performance advantages of AI due to the difficulty of sample collection, high cost of the collection, and lack of universality which caused by the complexity of the environment.Therefore, academia and industry introduce generative adversarial network (GAN) into the design of wireless networks.The powerful feature learning and feature expression ability of GAN can generate a large number of generated samples, which realizes the expansion of the wireless database.The introduction of GAN can effectively improve the generalization ability of AI models for wireless networks.Owing to the excellent performance of GAN, the generative model represented by GAN has attracted increased attention in the field of wireless networks, and rapidly became the new research hotspot of 6G networks.Firstly, the principle of GAN and its different versions of improved derived models were summarized.Then, the framework, advantages and disadvantages of each model were analyzed.Secondly, the research and application status of these models in wireless networks were reviewed.Finally, the research trends of GAN were proposed for the 6G network requirements, which provided some valuable exploration for future research.…”
